Application filed November 2, 1910. Serial No. 590,333.

Toall whom it may concern:

Be it known that I, lViLLL-m H.- BELL, 'a

citizen of the United States, and a resident of the city of New York, borough of Man hattan, in the county and State of New York, have invented anewand Improved Automobile-Chassis, of which thefollowing is a full, clear, and exact description.

Among the principal objects which the present invention has-in view are'z to provide a supporting frame for an automobile frame connecting the wheel and axles, said body constructed and arranged to provide resilient supports, the vibrations whereof are slowed; and to provide resilient niembers'to normally separate the structural members thereof.

One embodiment of the present invention is disclosed in the structure illustrated in the accompanying drawings, in which like parts in-all the views, and-inwhich Figure'l is 'a vertical longitudinal sectionof an automobile chassis, showing inside elevation side bars constructedand arranged in accordance with the presentinvention,

and on one side of the said chassis; Fig. 2 is a vertical section taken on'the line 2--2 in Fig. 1; Fig. 3 is a modified formof the.invention, shown as a vertical cross section taken through one .of the said'bars;' and Fig. 4 is'a modified form of the invention, showing in side elevation side bars constructed and arranged in accordance with the present invention employinga plurality of riding springs.- I ,3

The SldB ar 9 shown in the drawings 18 of any approved construction. .It is pro-.

. vided with bowed ends 10, 10, tothe'lower ends whereof, bymea ns of thill ,pins 11,- 11,

are connected swing bars 12 and 13. The

swing bars 12 and 13 are each pivotally connected with the axle of the automobile farthest removed from the end of the side bar. 9

to which the 'said swingbar is connected;

For instance, the swing bar12' is connected with the steering axle A oi the automobile. by means of a-thill pin 14, while the swing bar 13 is connectedwitli the driving axle B," being provided with an. eyelet end '15 through the eye of which the sleeve .-C is' passed. The swing bars 12 and 13 are each provided with similarly formed 's lidi'ng plates 16 and 17 Theplat'es 16.and l7 are .bars 12-a nd 13 respectively,

' In the formotthe invent-ion shown inconstructed .to bear upon each other in guided relation, and are ]O1I1QCl by a con-- axle B, orthe center of the eye in 'the end 15 of the swing bar 13. 1 In all positions the pin 18 maintains theseparation of the axles .A and B andf the parallelity thereof, said pin beingsupported by both said plates 16 and 17 and in the slots 19 therein.

It will be noted that by the constructionwhere the bowed ends 10, 10 are dropped to near the level of the axles A, B, and that where the swing bars 11 and 13 are 'providedwith a straight extension substantially aliiiedwith the said axles, the arcs of movement of the pins'll, 11 and the axles A and B are approximately vertical and parallel. By means ofthis construction and by reason of tl1e. 'connection between the swing arn'1sj12 and 18 by the pin 18, the.

wheel bearing ends-ofthejaxles are maintained equally distant in all bration of the wheels E,

Disposedbetween each of the swing bars 12 and 13 and sidebar 9'are elliptical riding positions of visprings 20,- 20. .Theyspi-ings 20, 20 are. shown in the drawings as laminated leaf springs of usual construction. The springs 20 are pivotally, connected by means of pivot linksfzl, 21- to the sidebars 9, 9, and by means of clamp'plates 22. tof'thwnziiig Figs. 1 and 2 of the drawings the springs 20, 201 are disposed on opposite sides of the swing bars'12 and 13. In this form theside baif9 is provided with lateral brackets 23, 23 between which and the upper clamp plate 22 .are coiled. bolster springs 24:, 94. The bOlSteiSPllHgS 24;, 24:v are constructed in any approved form, and as Tusu'al in the operat-ion of such. springs,- -exer t rapidly increasing resistances asthe springs' are-compressed .1aterally.-.- 4 v 1 -In.tl1e'" form oii the invention shown .in

Fig. '3, the springs and 24 are disposed on one side only of the side bar 9, and as shown, preferably at the outside of the said ar.

In the formof the invention shown in Fig. 4 of the drawings, the leaf springs 25 are connected by means of links 26, 26 to the swingbars-and to the axle A. By mounting I the swing bars 12 and 1 3 in this manner a greater resiliency is provided in the hang ing for the automobile body.

The; operation of the invention is as follows:- When in the operation of the auto- .mobile 'the steering wheel D overrides an obstruction, the said wheel, and the axle A thereof, are lifted freely. The leverage of the side bar12'bei'ng fulcrumed on-the thill' pin 11 at the oppositeend of the car, compresses easily the elliptical springs 20110- cated overthe driving axle B'. The'oscillation of the wheel D and the axle A from the controlling pivot pin of the bar 12, which is the-thill pin 11 at the rear of the automo- .2 bile, being elongated, the vibratory efiect or transmission to the automobile body is very slight. Hence, in an automobile running gear having hangers constructed as above set forth the wheels would override an obstruction with little or no appreciable jar on the chassis or body of the} automobile. It is also true that when in the operation of the automobile the steering wheels D pass over a depression in the road, the wheels being at the long end of a lever formed by the .35

side bars 9, 9,v would be'forced quickly into the said depression by the springs 20, a slight movement only of the springs being required to produce a long oscillation of 11 the wheel D and axle.

h It will also be observed that by the dropping of the wheels D intothe said depression, the front of the Y body of the automobile is not depressed, this being supported by the swing bar 13 which is connected to the driving axle B. If the depression be sufiiciently long for the body to settle, the rear of the body, which is supported by' the bars 12 and the wheel D, settles first. WVhen the driving wheels of the automobile pass into the depression the front of the body is lowered.

The above described action whereby the rear of the body of the automobile is loweredv in advance of the'front of the body,

I ea'rrymg wheel axles; a plurality of swing bars connecting one of said axles' and that end of one ofsaid side bars which is remote.

from the axle to which the said swing bar is connected; a plurality. of springs interposed between said swing bars and said side bars at nearthe pivot connection thereof; and riding plates formed on said swing bars at the mid section thereof, {and provided with slots formed therein, the curveof said slots being formed from the pivot connection of each of said swingbars and the axle whereupon each is mounted.
